when trying to install guzzlehttp (composer require guzzlehttp/guzzle) on a suitecrm-8 instance I get the following message
Problem 1
- Root composer.json requires guzzlehttp/guzzle ^7.5 -> satisfiable by guzzlehttp/guzzle[7.5.0, 7.5.x-dev].
- guzzlehttp/guzzle[7.5.0, ..., 7.5.x-dev] require guzzlehttp/psr7 ^1.9 || ^2.4 -> found guzzlehttp/psr7[dev-master, 1.9.0, 1.x-dev, 2.4.0, ..., 2.4.x-dev (alias of dev-master)] but the package is fixed to 2.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
Problem 2
- guzzlehttp/guzzle[7.5.0, ..., 7.5.x-dev] require guzzlehttp/psr7 ^1.9 || ^2.4 -> found guzzlehttp/psr7[dev-master, 1.9.0, 1.x-dev, 2.4.0, ..., 2.4.x-dev (alias of dev-master)] but the package is fixed to 2.1.0 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
- codeception/module-phpbrowser 1.0.2 requires guzzlehttp/guzzle ^6.3|^7.0 -> satisfiable by guzzlehttp/guzzle[7.5.0, 7.5.x-dev].
- codeception/module-phpbrowser is locked to version 1.0.2 and an update of this package was not requested.
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
You can also try re-running composer require with an explicit version constraint, e.g. "composer require guzzlehttp/guzzle:*" to figure out if any version is installable, or "composer require guzzlehttp/guzzle:^2.1" if you know which you need.
I would like to install the stable version of guzzlehttp. In this case, what is the recommended solution?
Thanks in advance
